My conversation with Isla at dinner tonight:
Isla: Mommy loves the baby.
Me: I love both my babies.
Isla: No, Mommy doesn't love (pause) two babies. Mommy (another pause) loves one baby.
Me: Mommy loves Isla, but Mommy can love another baby too.
Isla: No, Mommy doesn't love (pause) other baby. Mommy loves dis baby. Dis one. (at which point she emphatically pointed to herself).
